[0014]1. In use, first, open the lockable cabinet door and neatly place the materials or tools to be transported or the tools into the storage box according to the work requirements, thus preventing the materials or tools from falling due to bumps during the operation. The bottom of the storage box is rigidly connected to the connecting plate through a damping spring. The damping spring is in a pre-compressed support state. When the work vehicle travels on a bumpy road and generates vibration, the road impact force will be transmitted to the damping spring through the bottom plate and the connecting plate. The spring absorbs part of the impact force through its own elastic deformation. If the impact force is upward, the spring is further compressed to buffer the vibration. If the impact force is weakened, the spring slowly returns to its original position, preventing the storage box from shaking violently with the vibration. At the same time, the damping structure can suppress the high-frequency rebound of the spring and prevent secondary vibration caused by the repeated extension and contraction of the spring, thereby effectively weakening the vibration transmission during the operation and preventing the items in the box from being damaged due to violent vibration. In addition, the sliding grooves on both sides of the storage box and the sliding frame of the connecting plate, the sliding frame and the sliding groove of the bottom slide plate and the bottom plate connecting groove form multiple limits, restricting its horizontal displacement. Together with the vertical buffering effect of the damping spring, it achieves all-round stable load bearing of the storage box.

Description
Technical Field
[0001] This utility model relates to the field of work vehicle technology, specifically a multi-functional unmanned work vehicle. Background Technology
[0002] Unmanned vehicles are intelligent mobile devices that can autonomously complete tasks such as material transportation, site inspection, and operation assistance without real-time human control. Their core function is to reduce labor costs and improve operational efficiency, while adapting to complex or dangerous scenarios that are difficult for humans to access, meeting the automation needs of agricultural production, warehousing and logistics, municipal operation and maintenance, and other fields. However, traditional unmanned vehicles have two main drawbacks. First, they are limited in function and lack the ability to adapt to complex road conditions such as uneven or gravel roads. When driving on uneven roads, they are prone to chassis collisions and wheel suspension, affecting operational stability. Second, they are easily affected by bumps during transportation, and items are prone to displacement, collisions, or even falling. This is especially true for fragile items or precision tools, which are easily damaged, thus increasing operational losses. Therefore, those skilled in the art have provided a multi-functional unmanned vehicle to solve the problems mentioned in the background. Utility Model Content
[0003] The purpose of this utility model is to provide a multi-functional unmanned operation vehicle to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A multi-functional unmanned operation vehicle includes a base plate, a mobile power structure, and a steering structure. Two first through slots are opened on one side of the top of the base plate, and two second through slots are opened on the other side of the top of the base plate. A connecting plate is fixedly connected to the middle of the top of the base plate. The mobile power structure is fixedly connected to one side of the top of the connecting plate, and the steering structure is movably connected to the other side of the top of the connecting plate.
[0006] As a further embodiment of this utility model: the mobile power structure includes a first fixed plate, a first limiting plate, a first mounting plate, a moving wheel, a connecting shaft, a first motor, a rotating shaft, a first cylinder, and a first protective frame.

The two sides of the connecting shaft pass through both sides of the first protective frame and are fixedly connected to a rotating shaft. The connecting shaft is rotatably connected to the first protective frame. The side of the rotating shaft away from the first protective frame passes through one side of the first mounting plate and is fixedly connected to a moving wheel.
[0008] As a further embodiment of this utility model: the steering structure includes a second fixed plate, a fixed shaft, a second cylinder, a second limiting plate, a steering wheel, a second mounting plate, a connecting column, and a second protective frame. A second motor is fixedly connected inside the second protective frame. A round shaft is fixedly connected to the power output shaft of the second motor.

The round shaft is rotatably connected to the second protective frame. The other side of the fixed shaft passes through the top of the connecting plate and is fixedly connected to a second fixed plate. The fixed shaft is rotatably connected to the connecting plate.
[0009] As a further embodiment of this utility model: two second cylinders are fixedly connected to the bottom of the second fixed plate. The power output end of each second cylinder passes through the first through groove and is fixedly connected to a connecting column. A second limiting plate is fixedly connected to the other side of each connecting column. A second mounting plate is fixedly connected to the bottom of each second limiting plate. A rotating shaft is fixedly connected to each second mounting plate. A steering wheel is rotatably connected to each rotating shaft.
[0010] As a further embodiment of this utility model: two sliding frames are fixedly connected to the inner walls of both sides of the connecting plate, and several damping springs arranged at equal intervals are fixedly connected to the top center of the connecting plate. A placement box is slidably connected to the connecting plate, and two sliding grooves corresponding to the sliding frames are opened on both sides of the placement box. The sliding grooves are slidably connected to the sliding frames, and the bottom of the placement box is fixedly connected to the damping springs.
[0011] As a further improvement of this utility model: sliding plates are fixedly connected to both sides of the bottom of the placement box, and two sliding frames are fixedly connected to the inner side of each sliding plate. Lockable cabinet doors are hinged to both edges on one side of the placement box. A groove is provided on the top of the bottom plate and between the two first through slots, and the groove is fixedly connected to the second protective frame on the steering structure.
[0012] As a further improvement of this utility model: both sides of the base plate are provided with connecting grooves adapted to the slide plate, and two sliding grooves corresponding to the slide frame are provided on one side of the inner wall of the connecting groove, and the sliding grooves are slidably connected to the slide frame.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. In use, first, open the lockable cabinet door and neatly place the materials or tools to be transported or the tools into the storage box according to the work requirements, thus preventing the materials or tools from falling due to bumps during the operation. The bottom of the storage box is rigidly connected to the connecting plate through a damping spring. The damping spring is in a pre-compressed support state. When the work vehicle travels on a bumpy road and generates vibration, the road impact force will be transmitted to the damping spring through the bottom plate and the connecting plate. The spring absorbs part of the impact force through its own elastic deformation. If the impact force is upward, the spring is further compressed to buffer the vibration. If the impact force is weakened, the spring slowly returns to its original position, preventing the storage box from shaking violently with the vibration. At the same time, the damping structure can suppress the high-frequency rebound of the spring and prevent secondary vibration caused by the repeated extension and contraction of the spring, thereby effectively weakening the vibration transmission during the operation and preventing the items in the box from being damaged due to violent vibration. In addition, the sliding grooves on both sides of the storage box and the sliding frame of the connecting plate, the sliding frame and the sliding groove of the bottom slide plate and the bottom plate connecting groove form multiple limits, restricting its horizontal displacement. Together with the vertical buffering effect of the damping spring, it achieves all-round stable load bearing of the storage box.
[0015] 2. Next, start the first motor to drive the drive gear to rotate. Since the drive gear and the driven gear are in a meshing state, the driven gear rotates synchronously with the drive gear and drives the connecting shaft fixed at its center to rotate. The two ends of the connecting shaft pass through both sides of the first protective frame and form a rotational fit with the protective frame through bearings to ensure that there is no deviation or jamming during rotation. The two ends of the connecting shaft are fixedly connected to the rotating shaft respectively. The rotational power is transmitted to the rotating shafts on both sides through the connecting shaft. The end of the rotating shaft away from the connecting shaft passes through the first mounting plate and is rigidly connected to the moving wheel. Finally, it drives the two moving wheels to rotate synchronously around their own axis. By controlling the forward and reverse rotation of the first motor, the forward or reverse rotation of the moving wheel can be realized, thereby driving the work vehicle to move forward or backward.
[0016] 3. Start the second motor to drive the circular shaft to rotate. The circular shaft passes through the top of the second protective frame and is rotatably connected to the protective frame through a bearing to ensure stable rotation. The top of the circular shaft is fixedly connected to the fixed shaft. The fixed shaft passes through the connecting plate and is rigidly connected to the second fixed plate. Therefore, the rotational power of the circular shaft is transmitted to the fixed shaft and the second fixed plate in sequence, causing the second fixed plate and the second cylinder, connecting column, second limit plate and second mounting plate connected below to rotate around the axis of the fixed shaft. Since the steering wheel is rotatably connected to the second mounting plate through the rotating shaft, when the second mounting plate deflects, the orientation of the steering wheel changes accordingly, thereby guiding the work vehicle to turn in the preset direction. This allows for precise adjustment of the steering wheel deflection angle, enabling the work vehicle to make small-radius turns or make precise direction corrections, meeting the steering requirements in complex working environments.
[0017] 4. By synchronously extending the first and second cylinders, the moving wheels and steering wheels can be pushed downwards, thereby raising the chassis height formed by the base plate and avoiding collisions between the chassis and protruding parts of the road surface. When the road surface is sunken, the two cylinders are instructed to synchronously shorten, driving the wheels upwards and lowering the chassis height, ensuring that the wheels always remain in contact with the ground and avoiding insufficient power or steering failure due to suspension. In addition, if the work vehicle needs to cross obstacles in the work scenario, the height of one side of the wheel can be adjusted by adjusting the extension and retraction of one side of the cylinder, assisting the work vehicle to cross obstacles smoothly. During the entire height adjustment process, the first through groove on the base plate provides clearance for the extension and retraction of the second cylinder, and the second through groove provides space for the extension and retraction of the first cylinder, avoiding interference between the cylinder and the base plate and ensuring smooth adjustment.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Example 1
[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6This embodiment provides a multi-functional unmanned operating vehicle, including a base plate 1, a mobile power structure 5, and a steering structure 6. Two first through slots 13 are formed on one side of the top of the base plate 1, and two second through slots 14 are formed on the other side of the top of the base plate 1. A connecting plate 2 is fixedly connected to the middle of the top of the base plate 1. The mobile power structure 5 is fixedly connected to one side of the top of the connecting plate 2, and the steering structure 6 is movably connected to the other side of the top of the connecting plate 2. Two sliding frames 9 are fixedly connected to the inner walls of both sides of the connecting plate 2, and several equally spaced damping springs 8 are fixedly connected to the middle of the top of the connecting plate 2. A placement box 3 is slidably connected to the connecting plate 2. Two sliding grooves 10, corresponding to the sliding frame 9, are provided on both sides of the placement box 3. The sliding grooves 10 are slidably connected to the sliding frame 9, and the bottom of the placement box 3 is fixedly connected to the damping spring 8. The bottom of the placement box 3 is rigidly connected to the connecting plate 2 via the damping spring 8. The damping spring 8 is in a pre-compressed support state. When the work vehicle travels on a bumpy road and vibrates, the road impact force is transmitted to the damping spring 8 through the bottom plate 1 and the connecting plate 2. The spring absorbs part of the impact force through its own elastic deformation. If the impact force is upward, the spring further compresses. The spring contracts to buffer vibrations; if the impact force weakens, the spring slowly returns to its original position, preventing the placement box 3 from shaking violently with vibrations. Simultaneously, the damping structure suppresses the high-frequency rebound of the spring, preventing secondary vibrations caused by repeated spring contractions and extensions, thus effectively reducing vibration transmission during operation and preventing damage to items inside the box due to severe vibrations. Furthermore, the sliding grooves 10 on both sides of the placement box 3, the sliding brackets 9 of the connecting plate 2, and the sliding brackets 11 and sliding grooves 15 of the bottom sliding plate 7 and the connecting groove 16 of the bottom plate 1 form multiple limiting mechanisms, restricting horizontal displacement. These mechanisms, combined with the vertical buffering effect of the damping spring 8, achieve stable placement. The placement box 3 provides stable support from all directions; both sides of the bottom of the placement box 3 are fixedly connected to a sliding plate 7, and two slides 11 are fixedly connected to the inner side of the sliding plate 7; two lockable cabinet doors 4 are hinged to one side of the placement box 3; a groove 12 is provided on the top of the bottom plate 1 between the two first through slots 13, and the groove 12 is fixedly connected to the second protective frame 68 on the steering structure 6; both sides of the bottom plate 1 are provided with connecting grooves 16 that are adapted to the sliding plate 7, and two sliding grooves 15 corresponding to the slides 11 are provided on one side of the inner wall of the connecting groove 16, and the sliding grooves 15 are slidably connected to the slides 11.
[0028] Example 2
[0029] Reference Figure 1-6This embodiment is based on the previous embodiment, but differs in that the mobile power structure 5 includes a first fixed plate 51, a first limiting plate 52, a first mounting plate 53, a moving wheel 54, a connecting shaft 55, a first motor 56, a rotating shaft 57, a first cylinder 58, and a first protective frame 59. Two first cylinders 58 are fixedly connected to the bottom of the first fixed plate 51. The power output ends of the first cylinders 58 pass through the second through slot 14 and are fixedly connected to the first limiting plate 52. The bottom of each first limiting plate 52 is fixedly connected to the first mounting plate 53. A first protective frame 59 is fixedly connected between the two first limiting plates 52. A first motor 56 is fixedly connected to the top wall of the first protective frame 59. The power output shaft of the first motor 56 passes through one side of the first protective frame 59 and is fixedly connected to a drive gear. A driven gear is meshed with one side of the drive gear. A connecting shaft 55 is fixedly connected to the driven gear. The connecting shaft 55 passes through both sides of the first protective frame 59 and is fixedly connected to the rotating shaft 57. The rotating shaft 57 on the side away from the first protective frame 59 passes through one side of the first mounting plate 53 and is fixedly connected to the moving wheel 54. The first motor 56 is started to drive the connecting shaft 55 to rotate. The two ends of the connecting shaft 55 pass through both sides of the first protective frame 59 and form a rotational fit with the protective frame through bearings to ensure that there is no deviation or jamming during rotation. The two ends of the connecting shaft 55 are fixedly connected to the rotating shaft 57. The rotational power is transmitted to the rotating shafts 57 on both sides through the connecting shaft 55. The end of the rotating shaft 57 away from the connecting shaft 55 passes through the first mounting plate 53 and is rigidly connected to the moving wheel 54. Finally, the two moving wheels 54 are driven to rotate synchronously around their own axis. By controlling the forward and reverse rotation of the first motor 56, the moving wheel 54 can be rotated forward or backward, thereby driving the work vehicle to move forward or backward.Steering structure 6 includes a second fixed plate 61, a fixed shaft 62, a second cylinder 63, a second limiting plate 64, a steering wheel 65, a second mounting plate 66, a connecting column 67, and a second protective frame 68. A second motor is fixedly connected inside the second protective frame 68. A round shaft is fixedly connected to the power output shaft of the second motor. The other side of the round shaft passes through the top of the second protective frame 68 and is fixedly connected to the fixed shaft 62. The round shaft is rotatably connected to the second protective frame 68. The other side of the fixed shaft 62 passes through the top of the connecting plate 2 and is fixedly connected to the second fixed plate 61. The fixed shaft 62 and... The connecting plate 2 is rotatably connected, and two second cylinders 63 are fixedly connected to the bottom of the second fixed plate 61. The power output end of each second cylinder 63 passes through the first through slot 13 and is fixedly connected to a connecting post 67. A second limiting plate 64 is fixedly connected to the other side of each connecting post 67. A second mounting plate 66 is fixedly connected to the bottom of each second limiting plate 64. A rotating shaft is fixedly connected to each second mounting plate 66, and a steering wheel 65 is rotatably connected to each rotating shaft. When the second motor is started, it drives the round shaft to rotate. The round shaft passes through the top of the second protective frame 68 and rotates with the protective frame through a bearing. The connection ensures stable rotation. The top of the round shaft is fixedly connected to the fixed shaft 62, and the fixed shaft 62 extends upward through the connecting plate 2 and is rigidly connected to the second fixed plate 61. Therefore, the rotational power of the round shaft is sequentially transmitted to the fixed shaft 62 and the second fixed plate 61, causing the second fixed plate 61 and the second cylinder 63, connecting column 67, second limit plate 64, and second mounting plate 66 connected below to rotate around the axis of the fixed shaft 62. Since the steering wheel 65 is rotatably connected to the second mounting plate 66 through a rotating shaft, when the second mounting plate 66 deflects, the orientation of the steering wheel 65 will change. This change in direction guides the work vehicle to turn in a preset direction, thereby precisely adjusting the deflection angle of the steering wheel 65 to achieve small-radius turns or precise directional corrections, meeting the steering requirements in complex working environments. Through the synchronous extension of the first cylinder 58 and the second cylinder 63, the moving wheel 54 and the steering wheel 65 can be pushed downwards, thereby raising the chassis height formed by the base plate 1 and preventing collisions between the chassis and road protrusions. Furthermore, by individually adjusting the extension and retraction of one side of the cylinder, the height of one side of the wheel can be adjusted, assisting the work vehicle in smoothly crossing obstacles.
